* Use the register mapping feature bitCarl-Daniel Hailfinger2010-01-091-2/+0
| | | | | | | | | | | | | | | | | | | All functions which just call probe_jedec and then map flash registers are replaced by probe_jedec. All functions which call probe_jedec, map flash registers and do something else can at least eliminate mapping flash registers. Fix logic inversion in probe_jedec to map flash registers on success instead of on failure. Change a few TIMING_IGNORED to TIMING_FIXME where probe_jedec is used. Total savings: One probe function simplified, three probe functions eliminated. Corresponding to flashrom svn r839.

* Generify jedec functions by introducing an address maskSean Nelson2010-01-041-2/+2
| | | | | | | | | | | | | | | | | The patch converts jedec functions into mask-based generics which can be used for many chip provided the only changes are the addresses are converted from 0x5555/0x2AAA to 0x555/0x2AA or similar. The patch mostly changes jedec.c, but a few other files are changed because they use the jedec functions within their own functions. The patch also adds a copyright line to flashchips.c because of my recent work in converting AMD and Atmel chips to use struct erase_block. Corresponding to flashrom svn r828.

* Flashrom only checks for very few chips if the erase workedCarl-Daniel Hailfinger2009-06-151-11/+11
| | | | | | | | | | | | | | | | | | | And even when it checks if the erase worked, the result of that check is often ignored. Convert all erase functions and actually check return codes almost everywhere. Check inside all erase_* routines if erase worked, not outside. erase_sector_jedec and erase_block_jedec have changed prototypes to enable erase checking.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-4/+4
| | | | | | | | | | | | | | | | | | | Use chipaddr instead of volatile uint8_t * because when we access chips in external flashers, they are not accessed via pointers at all. Benefits: This allows us to differentiate between volatile machine memory accesses and flash chip accesses. It also enforces usage of chip_{read,write}[bwl] to access flash chips, so nobody will unintentionally use pointers to access chips anymore. Some unneeded casts are removed as well. Grepping for chip operations and machine memory operations doesn't yield any false positives anymore. Compile tested on 32 bit and 64 bit Linux. Corresponding to flashrom svn r519.

* Handle (un)locking of SST FWH chipsCarl-Daniel Hailfinger2009-05-111-3/+61
| | | | | | | | | | | | | | | | Add lock bit handling (printing, setting and checking) to SST FWH chips and abort any writes to locked sectors. Verbose mode gives you all the info. Normal mode only tells you of unlocking failed, but gives enough details to debug. Add a comment about flash register placement to flashrom.c.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now we perform direct pointer manipulation without any abstraction to read from and write to memory mapped flash chips. That makes it impossible to drive any flasher which does not mmap the whole chip. Using helper functions readb() and writeb() allows a driver for external flash programmers like Paraflasher to replace readb and writeb with calls to its own chip access routines. This patch has the additional advantage of removing lots of unnecessary casts to volatile uint8_t * and now-superfluous parentheses which caused poor readability. I used the semantic patcher Coccinelle to create this patch. The semantic patch follows: @@ expression a; typedef uint8_t; volatile uint8_t *b; @@ - *(b) = (a); + writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + readb(b) @@ type T; T b; @@ ( readb | writeb ) (..., - (T) - (b) + b ) In contrast to a sed script, the semantic patch performs type checking before converting anything.
